The Williams FM 557 is an FM Plus large-area dual FM and Wi-Fi assistive listening system with (4) FM R37 receivers. The new FM Plus integrates professional WaveCAST Wi-Fi audio server technology into a Williams Sound FM assistive listening system. End users can now listen with either an FM receiver or with their smartphone (via the WaveCAST Listening App). Along with this flexibility comes exceptional audio quality, as the FM Plus is built on a professional digital audio (DSP) platform.
The FM Plus uses the WaveCAST app to provide an easy-to-use, intuitive user interface. It is available on iOS or Android. Listeners easily select channel and volume level once their device is connected to the Wi-Fi network. The app does not work on FM Broadcasts.
True professional audio interface
The FM Plus can have most settings changed via the front panel interface or the hosted web interface. A remote programming guide is available upon request.
